  • Rocky mountain spotted fever, an infectious disease caused by another rickettsial agent

  • Feline leukemia virus (FeLV) infection

  • Feline infectious peritonitis (FIP), a viral disease of cats

  • Fungal infections such as cryptococcosis, histoplasmosis, blastomycosis and coccidioidomycosis

  • Toxoplasmosis, an infectious disease caused by a protozoa that completes its life cycle in cats

  • Hemobartonella felis, an infectious disease caused by a bacterial parasite that lives in red b
    lood cells

  • Leukemia, cancer of blood-forming tissues with spread of cancer cells through the bloodstream

  • Lymphoma, solid tumor of the lymphoid tissues that produce lymphocytes

  • Multiple myeloma, a tumor of the antibody-producing B-type lymphocytes

  • Myeloproliferative disease, cancer of the white blood cell producing bone marrow tissue

  • Other forms of cancer
